The first guide pipe 11 is provided therein with a water flow rotation guide 112 to receive the sewage entering from the water inlet 111 and to guide the sewage rotating at a high speed to move upward in a spiral ascending manner. Under the guidance of the water flow rotating guide device 112, sewage is subjected to first speed reduction from the first guide pipe 11 through the first flaring 12 and then enters the second flaring 14 from the second guide pipe 13 for second speed reduction, so that when muddy water reaches the top of the second flaring 14, large-particle sludge can be gradually settled to form a sludge filtering layer.

Referring to fig. 2, a sludge recovery cylinder 141 is disposed in the second flared end 14, and a sludge water ascending channel 142 is formed between the sludge recovery cylinder 141 and the second flared end 14. The muddy water can only be decelerated and ascended from the muddy water ascending channel 142 in the second flaring 14 due to the centrifugal force during the spiral ascending. The sludge recycling cylinder 141 is provided with a sludge leading-out pipe 143 which penetrates through the second flaring 14 and is communicated with the outside, and the sludge leading-out pipe 143 can be communicated with the outside, so that when the sludge recycling cylinder 141 is decompressed through the sludge leading-out pipe 143 to generate a vortex, sludge in a sludge filtering layer at the top of the second flaring 14 is acted by centripetal force, is sucked into the sludge recycling cylinder 141 and is discharged through the sludge leading-out pipe 143.

When the sewage is filtered, the sewage enters the first conduit 11 tangentially from the water inlet 111 after being subjected to flocculation treatment, so that the sewage generates rotary motion in the first conduit 11, and the water flow rotary guide device 112 guides the rotary water flow to spirally rise. When sewage passes through the first flaring 12 and the second flaring 14, the flow rate of the sewage is reduced, and the sewage reaches the top of the second flaring 14 through the muddy water ascending channel 142 under the centrifugal action, at the moment, large-particle sludge formed after flocculation is continuously settled under the action of gravity to form the sludge filtering layer 2 so as to intercept sludge with a certain particle size, and the filtering effect is achieved. In addition, the pressure is released through the sludge leading-out pipe 143, which causes vortex flow to be generated in the sludge recycling cylinder 141, so that the sludge of the sludge filtering layer 2 on the second flaring 14 is sucked into the sludge recycling cylinder 141 and discharged along the sludge leading-out pipe 143, and the effect of discharging clean water on the lower row of sludge is achieved.

When the sludge is discharged through the sludge discharge pipe 143, the sludge falls into the sludge storage chamber 31 and is discharged out of the high-efficiency separation device through the sludge discharge port 311.
